We're using a CuteEditor instance on one of our webpages and we keep getting the following error:

TypeError: Cannot read property 'value' of null [http://localhost/DevPatch/CuteSoft_Client/CuteEditor/Load.ashx?type=script&verfix=1003&file=spell.js:1]

When I take the url of the handler and navigate directly to it, I get the following:

I have no idea how to debug this, and the error is not descriptive at all.
